'Produce 48' Alum Lee Si An Captivates Viewers With Her Beauty on 'Single's Inferno' Season 4

"Single's Inferno" Season 4 has finally arrived, and one standout participant is stealing the show with her radiant beauty and K-pop roots.

Lee Si An, a former contestant on "Idol School" and "Produce 48," was the first to be introduced in the season's premiere on January 14. DEX and Jung Hanhae—two out of five mainstay hosts—couldn't help but praise her allure as she emerged in a stunning white, body-hugging dress.

In her introductory segment, Lee revealed what led her to join the reality show.

"I've constantly been in relationships. But right now, I'm single, which is a rare occasion," she confessed. "So I applied, because I wanted to experience a fiery, passionate romance."

"I want a whirlwind romance. A really emotional one," Lee said with a smile.

The former idol aspirant-turned-model hopes to meet someone who has a strong inner self in "Single's Inferno" Season 4.

"Because he'll have to dive into a whirlwind romance with me," Lee quipped.

As soon as the first four episodes dropped on Netflix, a plethora of comments erupted on theqoo, with K-netizens raving about her beauty. Some even compared her current looks to her time on "Produce 48."

"She's so f****** pretty. I hope 'Single's Inferno' can become a turning point for her career," a netizen enthused.

"Whoa... She's gotten even prettier now," another marveled, while one reminisced, "She looks matured now. She really nailed the 'Rumor' stage back in 'Produce 48.'"

One viewer fantasized about romance, saying, "She's stunning. Not only is she beautiful, but she's also very charming. I kinda wanna date her."

Meanwhile, a female user playfully asked, "Unnie, do you date women?"

Lee Si An rose to fame after competing in "Idol Produce" in 2017, where she ranked 16th in the finale, just shy of debuting with fromis_9. The following year, she joined "Produce 48," but she finished 30th and got eliminated on episode 11.

Sometime in 2020, Lee was a trainee under HF Music Company and was also part of the pre-debut team Happyface Girls. She also featured in D1CE's "Draw You" music video in the same year.

However, the group's debut fell off, and by 2021, all the members had left the agency.

Nonetheless, Lee forged a new path. In 2022, she signed with Leaders Model Agency to pursue a modeling career. She has appeared in numerous advertisements since then.
